<p>PURPOSE:To reliably prevent the occurrence of engine stole during rapid brake, by a method wherein, in an automatic starting clutch capable of continuously controlling a transmission capacity, control is made so that a clutch transmission capacity is lowered according to the working fluid pressure of a brake device. CONSTITUTION:An automatic starting clutch 1 mounted on the output side of a continuously variable speed change gear is disengaged through control of the feed and discharge of an oil pressure by means of a clutch control valve 2, and the control valve 2 is controlled by means of a signal oil pressure from a solenoid valve 4 controlled by an electronic control device 20. In this case, the electronic control device 20 is provided with a reference clutch oil pressure deciding means 20a to decide an reference clutch oil pressure 20 responding to the number of revolutions of an engine and a clutch oil pressure correcting means 20b to decide a correction oil pressure P responding to a brake liquid pressure according to correction oil pressure characteristics, and outputs a control signal provided by adding the reference oil pressure P0 and the correction oil pressure P by a means 20c.</p> |
